RICHARDS T. BROOKS, OF SYVARTHMORE, PENNSYLVANIA, ASSIGNOR TO THE KEYSTONE TYPE FOUNDRY, OF PHILADELPHIA, PENNSYLVANIA, A FIRM.

PEN CLAil/IIP IFOR RULING- IVIACHINES.

SPECIFICATION forming part of Letters Patent No. 747,127, dated December 15, 1903. Application filed March 20, 1963- Serial No. 148,725. (No model.)

To all whom, it may concern:

Be it known that I, RICHARDS T. BROOKS,

a citizen of the United States, residing at Swarthmore, in the county of Delaware, State ofPennsylvania, haveinvented new and useful Improvements in Pen-Clamps for Ruling- Machiues, of which the following is a specification.

Heretofore the clamping device of a rulingmachine has been made of wood and a strip of fabric employed to feed the ink to the pens, this piece owing to its moist condition causing warping and distorting of said clamps and irregularity in the position and action of the pens. Provision must, however, be made for the fastening of said piece to the pen beam or head, so as to retain the same in proper position.

My invention consists in forming such device of metal and applying thereto a piece of material which is adapted to have such piece. of fabric readily tacked or otherwise secured thereto.

Figure 1 represents a perspective View of a pen-clamp for a ruling-machine embodying my invention. Fig. 2 represents a longitudinal sectional view thereof. Fig. 3 represents a longitudinal section of a modification.

Similar letters of reference indicate corresponding parts in the figures.

Referring to the drawings, A designates a metallic beam or head, projecting forwardly from which is a pair of jaws with engaging screws, forming the pen-clampB. In the upper side or face of said beam is a recess 0, in which is fitted a piece or plate of wood D or other material of penetrable nature,said piece occupying a portion of the beam and having its upper face forming a continuity of that of said beam and being so disposed that when the strip of fabric for feeding the pens with ink is placed in position it may be tacked or otherwise properly secured to said piece D, and consequently to the beam A, the moisture of said fabric, as is evident, having no injurious effects upon the clamps.

The sides of the recess O and piece D are dovetailed, whereby said piece may be firmly held in position and conveniently removed 50 and reapplied, as desired.

In order to fasten the strip of fabric in position close to the pens, I employ the piece or plate E, of wood, which is connected with one of the upper clamps B, and having its upper face forming a continuity of that of the head A may have said fabric tacked or otherwise secured thereto similarly to the action of the piece D. The forward end of the head forms a vertical shoulder against which the rear end of said plate E is adapted to abut, so that said plate is set true against said head and a gap between said parts is prevented, the continuity of said piece and head thus being preserved. The piece E may also be dovetailed, as at E, to the adjacent clampbar B (see Fig. 3) for purposes the same as the piece D on the head A.

It will here be noted that the strip of inkfeeding material extends from the ink-pan over the head A and requires to lie flat on the latter and to be fastened tightly thereupon, so as to be prevented from curling or buckling, especially upward, whereby the adjustment of said strip with relation to said pan is not disturbed, this being accomplished by tacking or nailing the rear portion of said strip to the plate D. Again, said strip requires to be held down close to the pens and to be prevented from curling or buckling, especially upwardly,whereby the adjustmentof to said pens will be preserved. This is accomplished by tacking or nailing the portion forward of the head A upon the piece or plate E, the loose portion of said strip hanging true and uniformly over the pens.

Various changes may be made in the details of construction without departing from the general spirit of my invention, and I do not,therefore,desire to be limited in each case to the same.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. In a pen-clamp, a metallic head, a metallic pen-clamp extending forwardly of said head and a plate of wood occupying a recess in the top of said head, the upper faces of said plate and head beingflush or approximately flush.

2. In a penclamp, a metallic head, a me- I00 tallic pen-clamp extending forwardly from said head and a plate of wood superimposed on the upper member of said clamp and secured thereto and being flush or approximately flush with the upper face of said head.

3. In a pen-clamp for a ruling-machine a metallic head having a recess in its upper face, a plate of wood in said recess, a metallic clamp proper extending forwardly from said head and a plate of wood extending forwardly from said head and superimposed upon the upper member of said pen-clamp proper, said head and said plates having their upper faces forming continuities of each other.

4. A pen-clamp fora ruling-machine, consisting of a metallic head having a recess in its upper face, a plate of Wood in said recess, a shoulder on the frontof said head, a metallic pen-clamp proper extending forwardly from said head and aplate of wood superimposed upon the upper member of said penclamp proper, the same abutting against said shoulder,the upper faces of said head and said plates being continuities of each other.
